Pay attention to the following when using the vacuum drying oven:
1. The outer casing must be effectively grounded to ensure safe use.
2. It should be used in an environment where the relative humidity is ≤85% RH, there is no corrosive gas around, no strong vibration source and strong electromagnetic field exist.
3. The vacuum drying box studio is not treated with explosion-proof, anti-corrosion, etc., and it is not allowed to dry the items that are flammable, explosive and prone to corrosive gases.
4, the vacuum pump can not work for a long time, so when the vacuum reaches the requirements of dry items, the vacuum valve should be closed first, then the vacuum pump power supply should be turned off. When the vacuum is less than the requirements of the dry items, then the vacuum valve and the vacuum pump power supply are turned on, and the vacuum is continued. This will extend the life of the vacuum pump.
5. If the dry items are wet, it is better to add a filter between the vacuum drying box and the vacuum pump to prevent the humid gas from entering the vacuum pump and causing the vacuum pump to malfunction.
6. Dry items should be changed to weight after drying, and the volume is small (small granular shape). Vacuum should be added to the working chamber to add a barrier net to prevent the dry matter from inhaling and damage the vacuum pump or solenoid valve.
7. If the vacuum pump is normal and meets the technical requirements, but can not be vacuumed, open the door and use the wrench in the product accessory to tighten the door buckle on the box to close it and close the door again. In addition, after the vacuum drying oven is used for many times, there is a phenomenon that vacuuming cannot be performed. In this case, the door sealing strip should be replaced or the door latching distance on the box should be adjusted to solve the problem. When the temperature of the vacuum drying oven is higher than 200 °C, slow air leakage will occur. At this time, the back cover of the cabinet should be disassembled, the base of the heater should be loosened with an Allen key, and the sealing ring should be replaced or the base of the heater should be tightened.
8. If the rubber plug of the bleed valve is difficult to rotate, apply a proper amount of grease to the inside, such as Vaseline.
9, in addition to maintenance, generally can not open the left side of the box cover to avoid damage to the electrical control system.
10, vacuum drying oven should always be kept clean. Do not wipe the door glass with a reactive chemical solution. Wipe it with a soft cotton cloth.
11. If the vacuum drying oven is not used for a long time, wipe the exposed plating parts and apply neutral grease to prevent corrosion. Put on the plastic film dust cover and place it in the dry room to avoid damage to the electrical components. Affect.
